In sum, the present invention is according to the subnet mask of electronic equipment, MAC Address obtains the initial ip address corresponding with described MAC Address with preset algorithm, if initial ip address is available in IP address pool, then from described IP address pool, obtain the IP address identical with described initial ip address and this IP address is fed back to described electronic equipment, if initial ip address is unavailable in IP address pool, add-one operation is at least one times carried out to described initial ip address and obtains the final IP address that can be assigned with in described IP address pool, from described IP address pool, obtain the IP address identical with described final IP address simultaneously and this IP address is fed back to described electronic equipment, so MAC Address and IP address one_to_one corresponding can be got up by the present invention automatically, avoid occurring that different MAC Address corresponds on identical IP address, allow electronic equipments many again can obtain unique IP address, during management ip address, only need to arrange once, need not change again later, effectively raise utilance and the operating efficiency of each IP address, the present invention, without the need to the support by similar services such as dns servers, utilizes domain name to visit IP address, makes workflow simple, also can not exist because support region name does not cause the appearance of the analogues such as work obstruction, the present invention, by MAC Address and IP address being bundled, like this, would not occur that IP address is stolen and normally can not use the situation of network, effectively can ensure the safety of network and the application of user.And in some application using IP address, the IP obtained by the present invention only need be obtained once, later will without the need to being configured again, because IP is not in variation.So the present invention effectively overcomes various shortcoming of the prior art and tool high industrial utilization.
Above-described embodiment is illustrative principle of the present invention and effect thereof only, but not for limiting the present invention.Any person skilled in the art scholar all without prejudice under spirit of the present invention and category, can modify above-described embodiment or changes.Therefore, such as have in art usually know the knowledgeable do not depart from complete under disclosed spirit and technological thought all equivalence modify or change, must be contained by claim of the present invention.
